The invention discloses a service braking system based on intelligent hill-start assist. The service braking system is easy to operate and good in safety and comprises a first gas storage tank (1), a foot barking valve (4) and a service braking gas chamber (8) which are communicated through gas circuits; the service braking system further comprises a second gas storage tank (3), a differential-type relay valve (5), a magnetic valve (9), a first three-way valve (61), a hill-start assist controller (2) and a gas pressure sensor (11); a first control gas port (541) of the differential-type relay valve (5) is connected with a gas outlet of the foot barking valve (4) through a gas circuit, a gas inlet (51) of the differential-type relay valve (5) is connected with the second gas storage tank (3) through a gas circuit, a gas outlet (52) of the differential-type relay valve (5) is connected with the service braking gas chamber (8) through a gas circuit, a second control gas port (542) of the differential-type relay valve (5) is connected with the second gas storage tank (3) through a gas circuit by means of the magnetic valve (9), and the gas pressure sensor (11) is arranged on the gas circuit between the gas outlet of the differential-type relay valve (5) and the service braking gas chamber (8).
